摘要：Learner-Centered Design could assure a high quality level of e-learning, providing at the
same time efficiency, efficacy and satisfaction without high costs for design evaluation. Users could
benefit of a good instructional design, experiencing a successful and enjoyable usage. Such a
possibility stems from the fact that educational tools should not behave as frustration barriers. The aim
of this contribution is the individuation of quality factors which should characterize e-learning
interfaces, and their integration in a checklist for e-learning quality assessment.
